That text precedes the total designs to the Rack-and-pinion steering. Suffering the dint analysis, and calibrate the tired strength of the machine with the bent and tired strength in root of tooth. This article revised the unreasonable data of the steering. With the design of the Rack-and-pinion steering, selects the related spare parts. Such as bolt, bearing...etc. and draw the diagrams of the related spare parts in manual. Drawing the 6 precise of spare parts diagrams and 1 precise of the assemble diagram of Rack-and-pinion steering. Key words: Rack-and-pinion steering, design and calculation II 李牟嘉 齿轮齿条转向器设计
